Abstract

PARA UN PROCEDIMIENTO DE FABRICACION PARA UNA PIEZA DE MAQUINARIA DE FUNDICION CON UN DISPOSITIVO DE COJINETE CONFIGURADO EN VARIAS PIEZAS MEDIANTE FRACTURA, CON MUESCAS DE RUPTURA O DEPRESIONES (7) MOLDEADAS DURANTE LA FUNDICION DIAMETRALMENTE EN EL TALADRO DE COJINETE, SE PROPONE PARA UN PROCEDIMIENTO ECONOMICO QUE LAS DEPRESIONES (7) SE GENEREN POR MEDIO DE RESALTES SEPARADOS PREVISTOS EN EL NUCLEO CON CANTOS DE RESALTE LIBRES CONFORMADOS FIJAMENTE, CADA UNO CON UN RADIO CONFORMADOR DE ENTRE R = 0 MM Y R 0,45 MM EN LA ZONA DEL FONDO DE CADA DEPRESION QUE ACTUA COMO PUNTO DE FRACTURA.FOR A MANUFACTURING PROCEDURE FOR A PIECE OF CASTING MACHINERY WITH A BEARING DEVICE CONFIGURED IN SEVERAL PIECES BY BREAKING, WITH BREAKING NOTCHES OR DEPRESSIONS (7) MOLDED DURING THE PURPOSE DIEETALLY IN TALL THAT THE DEPRESSIONS (7) ARE GENERATED THROUGH SEPARATE HIGHLIGHTS PROVIDED IN THE NUCLEUS WITH FREE HIGHLY CONFORMED EDGES, EACH WITH A RADIO CONFORMER BETWEEN R = 0 MM AND R 0.45 MM IN THE BACKGROUND AREA OF EACH DEPRESSION THAT ACT AS A SPLIT POINT.
